Microscopic analysis of WTC dust by Nicholas Petraco, BS, MS, DABC, FAAFS, FNYMS at The New York Microscopic Society lecture held at AMNH 28 May 2003 45.1% Fiberglass, rock wool (insulation, fireproofing) 31.8% Plaster (gypsum), concrete products (calcium sulfate, selenite, muscodite) 7.1% Charred wood and debris 2.1% Paper fibers 2.1% Mica flakes 2.0% Ceiling tiles (fiberglass component) 2.0% Synthetic fibers 1.4% Glass fragments 1.3% Human remains 1.4% Natural fibers trace asbestos (it became illegal to use during the construction of the WTC) Other trace elements: aluminum, paint pigments, blood, hair, glass wool with resin, and prescription drugs were found. NOTES: Particles found were 1-4 micrometers in size. (In general, particles that are 5-8 microns are irritants, and those that are 104 microns are small enough to be airborne and ingested into the lungs.) Fiberglass particles are smaller than asbestos and lodge deeper into lungs creating more serious long-term health hazards than asbestos like white lung disease which will become more evident 5, 10, 20 years from 11 Sep 2001.

Why do we still use so much fiberglass if it's bad for you?

Because its normally very difficult to get fiberglass to pulverize like this. Whereas asbestos had a tendancy to eventually start to crumble by itself from heat cycles and wet/dry cycles.

I have a feeling we will see many more deaths related to 9/11 from respiratory problems.[V]

Adding radialogical components to this mix could not have made it much worse. Dropping the towers WAS a dirty bomb.

What ArmdLbrl said.....friability. Many forms of asbestos were non-friable, including things like brake pads, tile mastic, etc. They all went bye-bye because of friable asbestos like pipe insulation.
